Double "Hmm". I've tried to reproduce this but can't seem to find the right connections. I've tried with and without Svengali's Library OXP and BGS 2.0, but each time I get the right background on the details page. What OXP's are you running in this setup?

Upon further testing, it only appears to be missing on one particular save - my main commander, which was fine the night before.
Very strange! <scratches head> The problem must be at my end, so I'll have a tinker - the only change was the new nightly.

@Cody: I'm really sorry, but I can't reproduce your symptoms at my end. I've tried every combination I can think of, but no matter what I get the Xenon background on the parcel details page. The only way I can think this might be happening is if BGS ends up being loaded after Xenon UI Redux. In that scenario, the "lib_black.png" that BGS applies to the "long_range_chart_mission" and "short_range_chart_mission" settings via the screenbackground.plist file could take precedence over Xenon's entries for the same. One question: is Xenon UI Redux in the ManagedAddons folder, and BGS 2.0 in you Addons folder? If so, try moving Xenon UI Redux to the Addons and see if that helps.

I've tried it every which way. What has me scratching my head is the fact that it was fine one day, then the next day it wasn't.
As I said, a full re-install (which includes Windows) is on the to-do list. I'll not start tinkering again 'til that's all done.

A clean install of Win7, trunk nightly, and relevant OXPs, has done the trick - all is well again. For the record: BGS, Library, and Xenon Redux (UI and Resources) are currently in the AddOns folder, which is where they were yesterday when I still had the problem. <scratches head>

I'll leave them where they are for the time being, as I don't wish to tempt fate.
